Abstract

We summarize the recent research development of coal petrography and gas solid flow coupling mechanism. Solid flow coupling contains theories that seepage is imposed by both structure of coal and fluid. We also discuss theories that seepage is influenced by physical field and study the seepage theories influenced by physical field and coal structure. The solid fluid coupling model consists of eight parts including dual pore medium effect model, damage effect model, matrix shrinkage effect model, absorption expansion effect model, the water-air two-phase flow model, heat effect model, coal elastic effect model and drilling performance effect model. Furthermore, we analyze various modeling methods and their research content. It is concluded that present coal and gas solid gas fluid coupling models focusing on various factors, so some factors are neglected, like theories of seepage law under drilling vibration. Few studies now focus around gas strain-seepage coupling model under drilling vibration factors.
